The procession was forced to move slowly and cautiously through a rugged, mountainous district, from which no supplies of any sort could be drawn. The ox-waggon of the country had to be relied upon entirely for heavy transport. This mode of conveyance is somewhat characteristic of the progress of the tortoise; two miles an hour was the average rate of advance, and at most the shambling cattle succeeded in covering about twelve to fifteen miles a day. Of proper roads there were none. The country was a vast swamp after heavy rain, or, in fine weather, a mass of dry ruts and tracks, steep hills, difficult fords, and irritating boulders. Over all this had to be coaxed or goaded the patient oxen, or, still worse, the stubborn, obstinate mules which dragged the lighter carts, and which, like ignorant persons, sometimes jibbed for sheer jibbing's sake, true to the obstructionist instinct that belongs to the intellectually stolid. When a team of these strong yet strange beasts chooses to jib at a ford or in a pass, it takes some companies of infantry to haul the waggon on to level ground, and then, and only then, will they condescend to resume their labour. It may therefore be imagined that the progress of troops--dependent as they were for food and forage on the tempers of quadrupeds--was at this time slow and not always sure! However, troops and baggage were gradually concentrated at Springfield, while the Boers, who had spies everywhere, among boulders, in dongas, and upon the formidable height of Spion Kop, hurried about their preparations for the renewed and mighty tussle which was now pending. On the 10th of January Lord Dundonald, at the head of the Cavalry Brigade, started at dawn from Frere Camp. A few miles outside they came on targets erected by the Boers to represent a force advancing in skirmishing order, which showed that the enemy had evidently been indulging in rifle practice. The troops marched some twenty-four miles in a north-westerly direction to Springfield, through the country, which was one vast quagmire beset with the enemy, without mishap of any kind. There were thrilling moments when the enemy were known to be ensconced in neighbouring kopjes or hiding in the bush, but every precaution was taken, the country having been previously searched by scouts, and the whole movement so successfully carried out that the brigade at last was able to occupy a strong position dominating Potgieter's Drift on the Upper Tugela. Here at once extra defences were made, to ensure against surprise from the enemy, who, finding the rivers in flood, had retired to the north, and to enable Lord Dundonald's force to hold its ground, and thus render safe the passage of the river.
